Having only one lover, besides you,would allow her to feel safe, less anxious about having to find someone every time she wants some real dick. It would also allow her to go bareback as safety is a concern. A lot of women love to have their lovers ejaculate in them, why deny her that? Would she really leave you? You have given her the freedom that most men would bottle up. She has gotten a taste of that freedom along with your unconditional love, no need to leave you behind!
